TUBING ooMrnNY, or cmomnn rr, onrdncoaronerion 015" euro IBEAID comi Application filed March 22,1928. gserial 1m I years, a constantly increasing interest: in 5 beads for femlmne adornment. Beadsof every conceivable shape'and slze are strung.

on cords which are usuallycomposed of linen or silk. Beads are usually either jewels or semi-jewels, and being hard minerals, their movement on the cord which supports them results in a gradual fraying of the cord.

Frequently the cords break and if this occurs while the woman wearing them is on the street, it often becomes impossible to recover them. As the beads are'often matched and arranged in sequence according to their sizes, the loss ofone or more beads frequentlyruins the value of those which were' not lost. s

It is the object of my invention to provide a novel process for manufacturing bead cord which will result. in the provision of cord which will have both unusually great tensile strength and greatresistance power against fraying by the hard surfaces of the beads. Specifically it is the object of my, inventionv to provide a bead cord which will haveia fibrous .central strand of desired 'tensile strength and braided about the central strand, fine metallic'wire which possesses the necessary strength toresist fraying. V

The above and other objects to which reference will be made during the ensuing disclosure I accomplish by'that certain combination of parts of which I have illustrated a preferred embodiment.

Referring tothe drawings 7 Figure 1 is a diagrammatic view illustrative of the braiding operation.

Figure 2 is a diagrammatic view illustrative of the nature of the braid, the size of the thread and strand of'wire being ,much enlarged. 1 I p Figure 3 is a perspective viewof my preferied type of bead cord on a much enlarged sca e.

I have not attempted to show a complete braiding machine nor the method of drawing the central strand of fibrous thread through the former plate over tension rolls and onto the shipping spool as my invention does not slipping.

the same time, the wire '0 passes over the wire cl, and so on, as perthe diagram in Figure 2.

specifically relate. to. the braiding, machine per 'se, butmerely to a new-use for such a machine whichxresultsin my novel product. ,-It will be understoodthat Fdri-Ve'n;. ?01ls draw the various, fine metallicwires,-together 5 with the I fibrous. central -strand,,; through a platehaving a-hole Ofsubstanti'ally the :desired diameter ofthecord, fromiwhence the cord passes ontothe driven rolls, which may be faced with suitable material toprevent Several turns around the; rolls are-made :with 'the cord, after? W ich it is guided to a windingfshaft which rolls the cordiup 0naremovablespool upon whichz I c5 the cord is usually shipped. L

I have diagrammatically ure 1 an exemplary type of braiding in which 7 1 7 eight spools of finemetallicwire suchlas are indicated at 1 move in the path of a'figure 8 as at 2, and the spools indicated at move around a like path indicated at 4:.

The fine metallic wire is mounted on'these spool movement, said spoolspassing one an- V other and each spool 1 acting to lay its strand of Wire across the strand being dispensed from each spool 3.

The resultof movingfthe spools inthe man-' ner described and withdrawing the wire 5 through the forming plate at the same time is to form a square braid in which thewires cross, one'the other, at the points 7, 8, 9 and'tlO.

By referring to thestrand of wires as indicated at a, b, c, d, e, f, g, h, it will be noted that the wire a passes under the wire I), and at At the next braiding step each wire willltake the place of the next wire in the series, and will pass over its companion wire and this around the pattern.

a5 plan of braiding-will be continued all the way strand 5 will be drawn straight up from the intermediate space 11 between the spools, .0 1 f forming a center for the braid With the braid kfitting snugly about it After the braid is terials may also be usedQflI may completed the cord is Wound around rolls in Which the cord is naturally bent Without kinks or breakage occurriilg.

I have found that-using a fibrous core of silk such as D silk and using pliable number forty copper Wire for the Wire braiding that abead cord may be provided which will have a tension streng'thof over twelve pounds; The outer braided surface of copper will form a surface Which Will allow the head to slide around on the cord Without friction and with little or no tendency to fray the cord. 7

While I have specifically mentioned silk andcopper Wire substitutes for these mav p 7 use linen thread or other'thread to provide the tensile strength and I may'use silver ire, or Wire made-from aluminum, gold, iron; or various r alloys such as may be required forthe several purposes for-which the cord may be used. I 'Havingthus described my invention,'what I claim asnew and desire to secure by Letters Patent; is z-- bead -cord having a central strand ofn fibrous silk material having desired tensile strength Withstrands of pliable Wire braided thereaboiit'providing an outer surface for the cord which will resist frictional wear.
